Common Storage Units - JSS2 Computer Studies Lesson Note

Byte: A byte consists of 8 bits and is the fundamental unit for representing characters, numbers, and other basic data. Bytes are the building blocks for larger storage units.

Kilobyte (KB): One kilobyte is equivalent to 1,024 bytes. Kilobytes are commonly used to measure the size of small text files, images, and simple documents.

Megabyte (MB): A megabyte is equal to 1,024 kilobytes or approximately one million bytes. Megabytes are used to describe the size of larger files, such as music tracks or high-resolution images.

Gigabyte (GB): A gigabyte is composed of 1,024 megabytes or approximately one billion bytes. Gigabytes are often used to express the capacity of hard drives, SSDs, and the memory of modern computers.

Terabyte (TB): One terabyte is equal to 1,024 gigabytes or approximately one trillion bytes. Terabytes are commonly used to quantify the storage capacity of external hard drives, data centers, and large-scale cloud storage solutions.
